The stability, or instability, of the milk fat emulsion is very significant with respect to many physical and chemical characteristics of milk and dairy products. The stability of the emulsion depends strongly on the integrity of
一、核苷酸降解代谢 1. Uric acid is the excreted end product of purine catabolism in humans and many other animals For adenosine, the amino group is hydrolyzed before the ribose group is removed. For guanosine, the amino group is hydrolyzed
一、戊糖磷酸途径 In most animal tissues, the major catabolic fate of glucose 6-phosphate is glycolytic breakdown to pyruvate, much of which is then oxidized via the citric acid cycle, ultimately leading to the formation of ATP
